Agratas has terminated main construction contractor Sir Robert McAlpine, replacing it with Tonroe Group Ltd, after more than two years of work under a temporary letter of limited authority during which SRM billed about £400m. The factory’s construction budget of £800m is expected to be exceeded by at least £500m, and the internal start-of-production date of January 2028 is already likely to slip; it is the second contractor exit after TClarke left in March. Equipment for a critical electricity substation has not been ordered, a ring road is not started, and senior manufacturing-engineering staff have departed.
